Component Parts and Harness Connector LocationNKS003T0
System DescriptionNKS003T1
BCM (body control module) controls interior lamp, room lamp timer and interior lamp battery saver.
The following signals are input to BCM:
Door lock/unlock trunk open request signal from the Intelligent Key unit via CAN communication
Key cylinder switch status signal from power window main switch via power window serial link
Door switch signal from door switches (driver side, passenger side, rear LH and RH)
IGN power supply (signal) from PDU (power distribution unit)
ACC power supply (signal) from PDU
ROOM LAMP TIMER BASIC OPERATION
Applicable lamps
Room lamp system: map lamp, foot lamp (driver side and passenger side) and personal lamp (rear LH
and rear RH).
1. When getting on the vehicle
Lamps illuminate by timer operation when driver side door or passenger side door is unlocked.*
Lamps illuminate by timer operation after any door is open and then all doors are closed.*
Timer operation stops and lamps are OFF, when driver side door is locked or the push-button ignition
switch (push switch) is turned to ACC or ON from OFF.
*: This setting can be changed by CONSULT-II. Refer to LT- 2 8 5 , "
WORK SUPPORT (INT LAMP)" .

RH) opened and then closed.
Vanity mirror lamp LH and RH.
Operated side vanity mirror lamp is ON/OFF linked with vanity mirror opened and then closed.
Trunk room lamp (lower) and trunk room lamp (upper).
Trunk room lamps (lower and upper) are ON/OFF linked with trunk opened and then closed.
INTERIOR ROOM LAMP BATTERY SAVER FUNCTION
Applicable lamps
Room lamp system: map lamp, foot lamp (driver side and passenger side) and personal lamp (rear LH
and rear RH).
Step lamp system: step lamp (driver side, passenger side, rear LH and rear RH) and kicking plate illumi-
nation (driver side and passenger side).
Vanity mirror lamp LH and RH.
Trunk room lamp (lower) and trunk room lamp (upper).
If the any applicable lamp is left illuminated, BCM turns OFF the battery saver output power supply 30 or 60
minutes to prevent run down of the battery. (Factory setting time is 30 minutes. And timer setting can be
changed by CONSULT-II. Refer to LT-287, "
WORK SUPPORT (BATTERY SAVER)" .)
When the push-button ignition switch (push switch) is turned from ON to OFF, the timer is activated.
If any of the following door switch signal condition is changed with the push-button ignition switch (push
switch) in OFF position, the timer is activated when the change is occurred.

EXTERIOR LAMP BATTERY SAVER CONTROL
BCM activates the exterior lamp battery saver control function and turns off the exterior lamps to prevent bat-
tery from over discharge when the combination switch (lighting switch) is in 1ST or 2ND position and/or the
front fog lamp switch ON and the door lock operation is performed by keyless entry system.
CAN Communication System DescriptionNKS003TI
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNKS003TJ
Refer to LAN-34, "CAN Communication Unit" .
